It could be a leftover from some load of flashdrives that were used for promotion purposes. Better sell them cheap in a dollar shop than throw them away.
I'd just delete everything on that drive or - even better - format it. It's gone then.
I recently bought a flashdrive, just a cheap one from the dollar store, 16 gig, nothing fancy. I loaded a file onto it to print off for later and when i plugged it into my computer, there were three or four other files on it aside from the one that I had loaded. Now, I am what you may call severely technologically challenged, but I thought that the only file I should have seen was the one I had put on there? There was one labeled samsung something, which none of my devices are samsung devices. When I opened the folders there was a different code in each folder and one was in chinese I guess, it was asking my if I wanted to translate, but when i selected English, nothing happened. Anyways, my question is this, are there supposed to be other files on a brand new flashdrive if I did not upload them myself? If not, what are those codes for???
